Drop Hats.....

[CW325]

check the nut that spins on the strut. probably not tight enough causing the strut to move up and down when going over an uneven surface.

+1 This happened to me and caused a knocking noise.

I have a knocking on the passenger side after putting on my e90 strut hats. The spring must not be seated correctly or the top strut bolt isnt tight enough? Anything else I should check?

Just picked up a pair from the dealer. $12 each. Im using them on Jom Coilovers. Kinda pointless i know.

Its not just pointless, it wont work at all.

I'll assemble an IE camber plate with drop hats tomorrow to see how it goes. Just bought the hats on a whim.

i would say it would be a great idea to use with coilovers. you get the needed drop from the drop hats, but can also keep preload for the spring. many coilover companies say its important to keep preload if you want to have a somewhat comfortable ride.

no such thing as a pre-loaded E30 coilover, unless you get a kit with tender springs (not common). typical springs are 6" long, about half as long as a stock spring. they will maintain contact as long as you don't go full droop (and if you're taking your E30 over sweet jumps, you'll have other issues to deal with).

there's definitely no point to using a drop hat with a coilover spring, that doesn't (and can't) use the stock spring perch in the first place..

quick question regarding e90 drop hats. The e90 haps have metal ring on the bottom of the center hole, while the bottom of the e30 tophat is completely flat. When installing the e30 hat does that ring on the bottom of the e90 top hat affect anything? I just find it hard to believe that the e90 hats can drop the car 10mm's with that ring in there. Do you still leave in parts 7 and 8 in the picture below?

So far still only UUC and kmac camber plates confirmed to work?

Coilover springs are a smaller diameter than the stock springs. That's why there's no need for drop hats with coilovers...they won't fit. Besides, if you want it lower, just thread down the collars on the lower spring perch.

no point with coilovers, they don't usually use the stock perches either way.

Sigh**. My struts are pushed out further in my shock towers towards the fenders than with or w/o camber plates.... If anyone is gonna rub on the tower, it's me..... I bet your springs aren't lined up well in the perches and hats- anytime u jack ur car up, u need to watch for this and re- align ;) If there's any scrapping or binding going on, something else is worn out. Mine are REAL tight tolerances where yours wouldn't be as much ;)

I'm running HR race with sport billies and drop hats (not e90) IIRC theyre the Richard drop hats... I'm using UUC camber/caster plates that are 180 degrees turned out for my e46 control arms- I have no popping or any kind of problem... Bounce isn't even bad, in fact the car drive amazingly, and feels ultra smooth and stable at 130mph+

your using camber plates that is a completly different setup, anyone using stock strutmounts??

Thanks,

I added the e90 drop hats with H&R sports springs and now I have a spring popping noise when I slowly turn while driving. I guess I need to see if there is binding/scrapes in the strut tower. I also used the existing strut bearings that were about 2 years old. I didn’t add any extra washers just the e90 hats, existing washers, and a new lock nuts. Also have newer stock CABs.



Anyone have an idea to get these to work ???

One post suggested grinding the hat but they don’t seem to be larger that the strut mounts.

Would it be the angle of the e90 had compared to the stock hats?


Thanks for any ideas
